Major manufacturers, such as SOPREMA, offer shiplap edge boards for faster and easier installation. Essentially, these edges allow the boards to overlap and lock in place, ensuring there is no gap between them and thus minimizing the risk of air or water leaks. For installation on a 50,000 ft2 surface by a team of four installers, SOPREMA estimates a saving of 5 minutes per person per 100 ft2. The installation of shiplap boards is thus almost twice as fast as that of straight-edge boards.
Composed of a closed-cell foam core and coated with fibreglass-coated polymers, SOPRA-ISO PLUS SHIPLAP is a polyisocyanurate thermal insulating board with four shiplap edges that requires no support panel nor primer when used under COLVENT BASE 830 membranes. In addition, it saves time in several ways.
